Assembly type movable floor device with variable axial distance for automobile vibration test

Abstract

The invention discloses an assembly type movable floor device with a variable axial distance for an automobile vibration test, which comprises a rear wheel plate assembly and a front wheel plate assembly which are symmetrically arranged front and back, and is characterized in that the rear wheel plate assembly comprises a rear wheel main sealing plate, a rear wheel auxiliary sealing plate A, a rear wheel auxiliary sealing plate B, a rear wheel side guide wheel and a rear wheel sealing plate supporting cylinder; the rear end of the rear wheel main sealing plate is erected on the vibration cabin floor, and the front end of the rear wheel main sealing plate is directly erected on the vibration cabin floor; or the rear wheel auxiliary sealing plate A and the rear wheel auxiliary sealing plate B are erected on the vibration cabin floor; the front wheel plate assembly comprises a front wheel main sealing plate, a front wheel auxiliary sealing plate A, a front wheel auxiliary sealing plate B, a front wheel side guide wheel and a front wheel sealing plate supporting air cylinder, the front end of the front wheel main sealing plate is erected on the vibration cabin floor, and the rear end of the front wheel main sealing plate is directly erected on the vibration cabin floor; or the front wheel auxiliary sealing plate A and the front wheel auxiliary sealing plate B are erected on the vibration cabin floor. The device can meet the vibration test requirements of most small and medium-sized automobiles in the market.

Description

technical field [0001] The invention relates to automobile vibration test equipment, in particular to an assembled mobile floor device with variable axial distance for automobile vibration test. Background technique [0002] The vehicle vibration environment cabin test room needs to be equipped with a vibration plate. The vibration plate hidden inside the floor needs to meet the test cars with different wheelbases and wheelbases. Therefore, it is necessary to move within a certain range, correspondingly to meet the airtightness of the environmental cabin The mobile floor that needs to be equipped with insulation moves along with it. The following problems arise in the existing situation: [0003] 1) The simple mobile floor needs to manually adjust the position of the insulation board, divide the mobile floor into several support bars, and adjust the front and rear positions of the vibration plate according to the length of the wheelbase. This method is time-consuming. When ...

Problems solved by technology

[0003] 1) The simple mobile floor needs to manually adjust the position of the insulation board, divide the mobile floor into several support bars, and adjust the front and rear positions of the vibration plate according to the length of the wheelbase. This method is time-consuming. When moving the vibration plate, the support bars need to be first After taking it out, the vibrating plate needs to be operated by personnel after it is moved in place, and the stepless adjustment following the vibrating plate cannot be realized, and some wheelbases cannot be completely sealed, resulting in leakage of cooling

[0004] 2) The movable floor that automatically adjusts the wheelbase is generally fixed on the vibrating plate and moves along with the vibrating plate. However, since the moving floor needs to cover the entire opening and the forward and backward movement distance, a single moving plate is often too large, resulting in the inability to achieve a wide range. Wheelbase movement, for example, a 2500mm wheelbase can only move 600mm forward and backward, which does not meet the requirements of a small vehicle with a 1500mm wheelbase and a large vehicle with a 3500mm wheelbase
